Giannetto De Rossi (8 August 1942 – 11 April 2021) was an Italian makeup and special effects artist for motion pictures.
[3] Early in his career, De Rossi worked with a number of well-known Italian directors, including Sergio Leone and Federico Fellini.
De Rossi created a number of memorable effects in the two films, including the fetus-shaped Spice Guild Navigator seen floating in a tank in Dune and the Dagoth monster suit worn by André the Giant in Conan the Destroyer.
For the scene in which Rambo heals himself by igniting gunpowder inside of a torso bullet wound, De Rossi rigged a device which caused flame to burst from both Sylvester Stallone's stomach and back at once.
[7] De Rossi continued creating FX for both Italian and American cinema, until his death on 11 April 2021 (coincidentally the same day as fellow Lucio Fulci collaborator Enzo Sciotti).
